Yeah, backyard dirt SMH. Nice way to import bugs, poor way to grow your plants.
Don't use the seeds you paid good money for until you can get some proper soil.
Germinate by soaking seeds in water for 24 hours, then into a wet paper towel in a ziploc bag. If you set them on top of a warm (not hot) appliance like a refrigerator they will sprout faster, no hotter than 90F, I like 87F for sprouting beans. Check every 12 hours for sprouts! Plant sprouts with the tap root down (in proper seedling/starter mix). Don't over water, let the soil dry so the pot feels light before watering again. No food until they get the first multibladed leaves then start easy.
